Tubus Vega Evo rack, in great condition - only used on a couple of trips. It never carried more than about 15 pounds and is not very far off from new.
This is a great rack - super durable from a well-reputed brand, lightweight, and has a 55lb carrying capacity! You can use it for commuting or for touring around the world. Description here:
http://www.thetouringstore.com/TUBUS/VEGA%20evo/VEGA%20EVO%20PAGE.htmThe photos show the rack as it is now, and the rack mounted on my old bike, a Surly Troll. (and don't ask about my gear setup on that trip...)
Note that you cannot use this rack with most bikes that have disc brakes! It worked on the Troll because that frame is designed especially to allow the use of normal racks along with disc brakes, but most disc frames need disc-specific racks. This is the reason I'm selling the rack now.
